    <p>The following code should return all barcodes that are in the filter. however it seems to excecute the filter only on the first newrecord. </p> <p>the xml contains 5 newrecords with a barcode subelement ranging 1-5. if the filter contains 1,3 and 4 it returns 1 and if the filter contains 2,3 and 4 it returns a no records.</p> <p>Also the current setup (rpa.XMLData.Elements("NEWFILE").Elements("NEWRECORD") ) returns 5 rows. i have tried seeing what happens if i change this to comeback in a single row (rpa.XMLData.Elements("NEWFILE")) but this does the same in giving me back 1 result being the first hit, ignoring 3 and 4.</p> <p>is there a way to change this LINQ Statement to actually look through all the barcodes?</p> <p>edit: the information comes from a test atm so sorry if it looks a bit weird. i added info on the xml and the filter.</p> <p>also, i have found something extra on the problem if the </p> <p>filter contains 1,2,3 it works. filter contains 1,2,4 it will return 1 and 2 not 4.</p> <p>it seems to be breaking once it can't find a solution.</p> <pre><code>String string2Stream = String.Concat("2", Environment.NewLine, "3", Environment.NewLine, "4", Environment.NewLine, "End"); Stream reader = new MemoryStream(ASCIIEncoding.Default.GetBytes(string2Stream)); StreamReader read = new StreamReader( reader ); var filter = Enumerable.Where(StreamReaderToSeq(read), x =&gt; { int temp; return int.TryParse(x, out temp); }); var query = from p in rpa.XMLData.Elements("NEWFILE").Elements("NEWRECORD") where filter.Contains(p.Element("BAR_CODE").Value) select new { p.Element("BAR_CODE").Value }; </code></pre> <p>Underneath the xml i deleted alot of extra stuff that shouldn't be related.</p> <pre><code>&lt;?xml version=\"1.0\"?&gt; &lt;NEWFILE&gt; &lt;NEWRECORD num=\"1\"&gt;&lt;MAILSORT&gt;&lt;/MAILSORT&gt;&lt;BAR_CODE&gt;1&lt;/BAR_CODE&gt; &lt;/NEWRECORD&gt; &lt;NEWRECORD num=\"2\"&gt;&lt;MAILSORT&gt;&lt;/MAILSORT&gt;&lt;BAR_CODE&gt;2&lt;/BAR_CODE&gt; &lt;/NEWRECORD&gt; &lt;NEWRECORD num=\"3\"&gt;&lt;MAILSORT&gt;&lt;/MAILSORT&gt;&lt;BAR_CODE&gt;3&lt;/BAR_CODE&gt; &lt;/NEWRECORD&gt; &lt;NEWRECORD num=\"4\"&gt;&lt;MAILSORT&gt;&lt;/MAILSORT&gt;&lt;BAR_CODE&gt;4&lt;/BAR_CODE&gt; &lt;/NEWRECORD&gt; &lt;NEWRECORD num=\"5\"&gt;&lt;MAILSORT&gt;&lt;/MAILSORT&gt;&lt;BAR_CODE&gt;5&lt;/BAR_CODE&gt; &lt;/NEWRECORD&gt; &lt;/NEWFILE&gt; </code></pre>

    1. COPlease show a short but complete example - we can't see the XML or how you're building "filter" at the moment.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
